With years of experience in the technology industry, headlines about cyber attacks and data breaches stand out to me. Here’s your monthly roundup of the latest hacks and data breaches around the world. In this monthly series, I’ll share information and updates on the most recent hacks that I saw in the news, including causes, resolutions, and what you can do to protect your data.
Over the last several weeks, we saw what has now become the usual list of successful cyber attacks and data breaches across all industries, with government entities, healthcare and retail dominating the list.
It has been reported that 60 million USPS users’ data has been exposed in the result of an API authentication weakness. The API was set up so anyone signed in to their website would be able to query the system for account details of other users. Hackers had access to email addresses, usernames, street addresses, phone numbers and more personal information of as many as 60 million people. USPS is investigating this incident but does not believe that data has been leveraged to exploit customer records. Read More
The cyber attack might have happened in 2016, but last week Uber was fined by British and Dutch regulators for just over $1.1 million for failing to protect their customers data during a cyber attack. The data breach that occurred in October 2016, affected 32 million users, 82,000 of them from Britain. Full names, phone numbers, email addresses and passwords were among the data that was collected by hackers. This hack was the result of simple security flaws and could have been avoided. It is important to make sure your company's data is protected, if not it can lead to costly consequences. Read More
East Ohio Regional Hospital and Ohio Valley Medical Center were hit with a ransomware attack that disrupted emergency room operations. The emergency rooms were not able to take patients coming in via emergency responders but were still able to accept walk-in patients. Ambulance patients were brought to other surrounding hospitals not under the attack. The hospital system spokesperson said they have “redundant security,” therefore the hackers were only able to get through one layer of the network but not the second and it was resolved in a timely manner. It is extremely important for institutions within the healthcare industry to properly secure their data to avoid situations like this. Read More
Just in time for Black Friday and Cyber Monday, Amazon suffered a major data breach exposing customer names and email addresses. Affected customers have been notified via email but have not come forward with any additional information. Amazon reports that there is no action that needs to be taken by those affected. The customer names and email addresses were posted to its website due to a technical issue. Although it was not done by hackers, this shows that human error is a factor to account for when calculating risk. Read More

If the inline security tool goes off-line, the TAP will bypass the tool and automatically keep the link flowing. The Bypass TAP does this by sending heartbeat packets to the inline security tool. As long as the inline security tool is on-line, the heartbeat packets will be returned to the TAP, and the link traffic will continue to flow through the inline security tool.
If the heartbeat packets are not returned to the TAP (indicating that the inline security tool has gone off-line), the TAP will automatically 'bypass' the inline security tool and keep the link traffic flowing. The TAP also removes the heartbeat packets before sending the network traffic back onto the critical link.
While the TAP is in bypass mode, it continues to send heartbeat packets out to the inline security tool so that once the tool is back on-line, it will begin returning the heartbeat packets back to the TAP indicating that the tool is ready to go back to work. The TAP will then direct the network traffic back through the inline security tool along with the heartbeat packets placing the tool back inline.
Some of you may have noticed a flaw in the logic behind this solution! You say, “What if the TAP should fail because it is also in-line? Then the link will also fail!” The TAP would now be considered a point of failure. That is a good catch – but in our blog on Bypass vs. Failsafe, I explained that if a TAP were to fail or lose power, it must provide failsafe protection to the link it is attached to. So our network TAP will go into Failsafe mode keeping the link flowing.
Single point of failure: a risk to an IT network if one part of the system brings down a larger part of the entire system.
Heartbeat packet: a soft detection technology that monitors the health of inline appliances. Read the heartbeat packet blog here.
Critical link: the connection between two or more network devices or appliances that if the connection fails then the network is disrupted.
